First ever/important poll (Patreon)

Oh neat! First ever patreon poll!

I'm making this due to a recent development as of late and I wanted ya'lls two cents on it. Some of you may know that I've started to dip my toes into doing NSFW art and am officially accepting NSFW commissions.

I'm considering posting my nsfw art on here as patreon exclusives but I don't know how I should go about doing it. Should I add it to the $5 tier but have it marked/put a warning up before the actual drawing, or should I make it a separate tier. Maybe $10 or an alternative 18+ $5 tier. In which would be the same as the regular $5 but with the addition on nsfw posts (Though I don't know how often I'll be making nsfw.)

Lmk what you think is better
